Well, it's certainly not a 1s1s, but it uses TRIG! Yes, I, scmb1, have dragged math into vandalism. :D (But I won't be surprised if I'm not the first.) It's pretty simple to use. Press space while your mouse is on the paint can to grab it. Click to paint. Press space again to drop the can. Use the arrows on your keyboard or the sliders to change color and size. Like real spraypaint, the longer you spray on a spot, the darker it gets. It it's too slow, download and put on turbo speed. Have fun!
